gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been pregrobbed. However, this mechanism did not explain the behaviour of the pyrite concentrate. For this ore the
